-# TASK #1 > Integer Square Root

-# Submitted by: Mohammad S Anwar

-# You are given a positive integer $N.

-# 

-# Write a script to calculate the integer square root of the given number.

-# 

-# Please avoid using built-in function. Find out more about it here.

-# 

-# Examples

-# Input: $N = 10

-# Output: 3

-# 

-# Input: $N = 27

-# Output: 5

-# 

-# Input: $N = 85

-# Output: 9

-# 

-# Input: $N = 101

-# Output: 10
